Air Accident investigators were meanwhile at the crash scene all day, but faced difficulties moving the aircraft, which is believed to be embedded about four metres into the bog.

The Irish Parachute Club, which posted a statement on its website expressing its members’ “deep sadness”, was set to discuss the tragedy at emergency meeting.

The club said: “The Board of Directors, members and friends of the Irish Parachute Club are deeply saddened at the death of the occupants of the aircraft that was operating on behalf of the club.

“Our thoughts and prayers are with those affected. We would like to thank the Air Accident Investigation Unit and the emergency services who are continuing their investigation at this very difficult time.”
